During the operation of the refrigerator car, the fuel should not only support the operation of the vehicle, but also support the operation of the refrigerator car. The continuous operation of the cooling device needs continuous power input. The engine in the car is the key component to convert the fuel kinetic energy into kinetic energy. There is a kind of battery in the car structure to store a small amount of electric energy. Once the car is flameout, it is easy to run out of power. Unless there is a backup battery in the car or a nearby maintenance department for charging, the car can't start. It's easy to understand the huge fuel consumption of refrigerated vehicles. The power it needs is far more than that of ordinary vehicles. Such a large power will be converted into fuel consumption.
